Patent GB-188183-A (GB)
Abstract: 188,183. Young & Marten, Ltd., and Edwards, E. M. Oct. 21, 1921. Closed solid-fuel stoves.-In a closed solid-fuel stove of the type in which combustion occurs at the base of the fuel column, from which the distillation gases are drawn downwards whilst the combustion products pass to an annular chamber, a fire-pot resting on the grate bottom is provided with an internal flange which supports a firebrick or like lining in the stove. In another form an annular boiler is supported within the outer casing on the grate bottom. In the stove shown, the fire-pot f has an integral flange f<1> supporting the lining g. The grate bottom d slides out to dump the ashes. The fuel magazine h is supported by a flange h<1> fitting within a ring m supported by a rim m' on the top of the stove. Between the magazine and the outer casing b<2> is an annular space l through which the combustion products pass to the outlet k. Air is supplied through a hit-and-miss damper q above the ash box door, and further air orifices may be arranged at rand by a hit-and-miss grating in the cover n of the fuel magazine. The fire-pot and lining may be replaced by an annular boiler g<1> shown in broken lines.

Title: Television transmitter
IPC: H04N5/222
Filed: 1947-07-15
Abstract: 636,053. Television. RADIO CORPORATION OF AMERICA. July 15, 1947, No. 18846. Convention date, Aug. 29, 1941. [Class 40 (iii)] In a television transmission system in which the vision signals are accompanied by sound or audio signals, the latter are recorded prior to the television transmission, are transmitted with the vision signals, and are also reproduced at the locality of the scene being televised so that the action or movement may be made appropriate to the sound transmitted. As indicated in Fig. 2, electrical signals of the sound to accompany the video signals are fed from a record 38 and a pick-up 40 to an amplifier 42, the output of which is applied partly to loud-speakers 26 in a studio 24 and partly to an amplifier 44 and transmitter 46. The vision signals from transmitters 28, such as iconoscopes, are fed to an amplifier 30 and separate transmitter 32, appropriate synchronizing signals having been inserted. In a modification, Fig. 3 (not shown), the sound energy fed to the loud-speakers in the studio is slightly in advance of that fed to the transmitter assembly to provide a time interval for the person(s) being televised to carry out actions appropriate to the sound being transmitted. The sound record may be made on discs, as shown, on a magnetic wire or on light-sensitive film.

Abstract: 880,967. Feeding bagasse or coal to furnaces. BABCOCK & WILCOX Ltd. June 2, 1960 [June 2, 1959], No. 18871/59. Class 51 (1). [Also in Group XXX] Bagasse from a shoot 37 or coal from a shoot 36 is fed by a scraper conveyer 34 to a shoot 17 feeding a spreader stoker 5. The inclination of shoot 17 is adjusted by a lever 27 so that it delivers bagasse on to the top of the rotor 5 or discharges coal to a guide plate 20 which delivers coal horizontally to the top of the rotor 5. The divergent walls 61, 62 of the bagasse shoot 37 extend downwardly and rearwardly, the rear wall 62 terminating at a distance above the rear end of the scraper conveyer 34, a shredder feeder 64 comprising staggered rows of rods 68 being mounted between the lower end of the shoot wall 62 and the delivery end of the scraper conveyer 34. A gate 55 controls the delivery of coal from shoot 36 to a pivoted plate 53 which is moved by the slats of the scraper conveyer to cut-off the supply of coal, and deposits a predetermined quantity of coal between the slats. The shredder 64 and conveyer 34 are driven by a motor and a second motor drives the stoker rotor 5, which should rotate twice as fast for bagasse firing as for coal firing. For bagasse firing, the tipping plate 53 is raised clear of the feeder slats.

Title: Improvements in or relating to producing phenols from benzene hydrocarbons
Inventor: MONTARNAL ROGER
IPC: C07C37/58
Filed: 1960-05-27
Abstract: A monohydric phenol is formed when a mixture of a benzene hydrocarbon and water, saturated with oxygen and adjusted to a pH of 11 to 13 with a small quantity of an alkali hydroxide, is subjected to X-rays, or ultraviolet, beta- or gamma-rays, in the presence of a semi-conducting metal oxide or sulphide, suspended in a finely-divided state in the mixture, and subsequently acidifying the mixture to liberate the phenol.  In Example 2, an aqueous solution of caustic soda <FORM:0904697/IV (b)/1> is saturated with oxygen and benzene (0.8 g./litre), to which about 4% by weight of NiO has been added, and is irradiated with X-rays at 200,000 volts.  The speed of phenol formation is measured and compared with that when the reaction is carried out in the absence of NiO (see Example 1).  In Example 22, the dilute caustic soda solution is saturated with toluene (instead of benzene); and ZnS is used as sensitizer.  After the solution has been irradiated with X-rays, it contains the cresols.  In Example 17, the solution specified in Example 2, containing ZnO instead of NiO as sensitizer, is irradiated with ultraviolet rays; and the rate of formation of phenol is measured.  Example 23 describes the use of an electron accelerator as a source of radiation.  The irradiation of xylene, ethylbenzene and cumene is referred to.

Title: Heat stabilized field emission electron sources
IPC: H01J35/06
Filed: 1956-06-19
Abstract: 802,936. Discharge apparatus. RESEARCH CORPORATION. June 19, 1956 [July 1, 1955], No. 18952/56. Class 39(1). A field emission cathode is operated by a pulsed electric field and is also heated to a temperature sufficient to provide differential evaporation of contaminants and smoothing of the cathode surface but low enough to avoid thermionic emission and to prevent excessive dulling of the cathode through surface migration. In the arrangement shown, the cathode 11 which may be of tungsten, tantalum or rhenium is heated to a temperature of about 2000K by electron bombardment from a filament coil 56 which is heated by current from a transformer 53. A suitable potential is maintained between the filament 56 and the cathode support 12 by voltage from a source 57 and a high electric field is established at the cathode surface by applying pulses from a voltage pulser 15 to a ring anode 14. The maximum width of the cathode-support assembly 11, 12 may be of the order of 10-2 cm. A continuous electric field may also be maintained between the cathode and anode to prevent dulling in the case of very small cathodes. The filament 56 may be omitted and the cathode heated by passing a current from an external source through the supporting filament 12, or by radiation from nearby surfaces, induction heating, or resistive heating generated in the cathode itself by the passage of the emission current. The ring anode 14 may be replaced by a metallic plate to provide an X-ray generator. A number of cathodes may be mounted on the same supporting filament and operated in parallel or a " razor edge " emitter may be used. The cathode may be utilized in X-ray and h.f. generators, electron microscopes, voltage controllers, rectifiers, or electromechanical transducers.

[Class 103 (i).] In a vehicle brake of the kind that is applied by a spring and held off by vacuum, means are provided whereby when the holding off vacuum is destroyed a vacuum is established on the other side of the piston to assist the application of the brakes. The piston 5 is connected by a lever 3 to the brake operating shaft 6. The spring 11 which tends to apply the brake is normally retracted as shown by vacuum in the chamber 9 established through the passage 29 past the non-return valve 27 and the pipe 28 which may be connected to the induction pipe of the vehicle engine. The chamber 10 is normally open to atmosphere through pipe 26 and valve-controlled passage 25. To apply the brake the cam 16 is turned whereby the valve 18 is unseated to connect the chamber 9 to the atmosphere while at the same time by the engagement of the stem of this valve with the stem 21 of the valve 22 the latter valve. is moved from its seat to connect the chamber 10 to the suction pipe 28, this valve being also engaged with its seat 23a to cut off the chamber 10 from the atmosphere. The stem of the valve 18 has a conical end 30 which gradually closes the passage 29. Valve 18 is opened thus permitting of a gradual application of the brakes.
